It talks about the huge prevalence of Vitamin D deficiency among all age groups. It is not just common among people living in countries with winters predominantly but also among those who are living in countries with abundance of sunlight. The particular reason behind was very few good quality sources of Vitamin D. That’s why the Science Advisory Committee of nutrition recommended the UK residents to take Vitamin D supplements. Moving on, it also stated the relationship between covid-19 and nutrition, mentioning that Vitamin D is no magic bullet against COVID-19. In fact, it is adequate nutrition, that includes foods rich in Vitamin D or supplements and other nutrients, that can support the immune system. Also, maintaining a healthy weight, as well as having a healthy lifestyle which includes regular physical activity, safe exposure to sunlight, stress management and adequate amounts of sleep are all important. It also mentioned that no one food or single nutrient can combat infections or support the immune system.
